【摘要】 本文采用溶胶-浸渍技术在玻璃纤维表面包覆了TiO2,并研究了制备工艺对其结构和光催化性能的影响。结果表明,用pH=2浓度为0.1 mol/L的TiO2溶胶将经过硫酸双氧水预处理的玻璃纤维浸胶2次,并在空气中450℃热处理2h,可以获得具有最高光催化性能的TiO2附载玻璃纤维材料。更多还原

【Abstract】 In this paper, TiO2 was dip-coated on fiberglass. The effect of preparation process on the microstructure and photocatalystic activity was investigated. Results indicated that if the fiberglass was treated by boiling in H2SO4/H2O2 and then dip-coated for 2 times in TiO2 sol with concentration of 0. 1 mol/L and pH value of 2. 0, and finally was annealed at 450℃ in air for 2h, optimum photocata-lytic activity of the sample can be obtained.更多还原
